Symptoms of Exposure: Coughing, sneezing, mild skin redness, mild gastrointestinal distress
Flammability: Not flammable
Extinguishing Media: Use any media suitable for surrounding fire, such as water spray, foam, dry chemical, or CO2
Special Firefighting Procedures: Avoid generating dust, wear self-contained breathing apparatus and protective gear, minimize use of water if fine powder present to prevent spreading
Combustion Products: Carbon oxides, strontium oxide, may emit irritating fumes as decomposition products
Explosion Hazards: Fine dust can create combustion hazards in air, though risk is minimal due to low volatility
Thermal Decomposition: Begins above 200°C, monitor for smoke or fumes
Personal Precautions: Ventilate area, use dust mask or respirator, wear gloves and protective eyewear
Environmental Precautions: Avoid release to drains or soil, contain spills to prevent entry into waterways
Cleanup Methods: Sweep up and collect into suitable containers for disposal, minimize dust generation by moistening dust, clean area with water after initial removal
Emergency Procedures: Isolate area, prevent unauthorized personnel from entering
Recommended Equipment: Use HEPA vacuum or damp sweeping for larger spills, dispose of absorbent materials properly
Precautions for Safe Handling: Use in well-ventilated space, wear gloves and eye protection, avoid generating dust during transfer or weighing
Safe Storage Conditions: Store in tightly closed containers, in a cool, dry, well-ventilated area away from incompatible materials
Incompatibilities: Avoid strong acids and oxidizers
Storage Temperature: Ambient, below 30°C recommended
Hygiene Measures: Wash hands after handling, avoid eating or drinking when working with the material
Packaging Materials: Use containers made from HDPE, glass, or compatible materials that prevent ingress of moisture
Segregation: Store away from food and beverages, keep away from acids to prevent unwanted reactions
Exposure Limits: No occupational exposure limit established for strontium citrate, keep airborne dust below nuisance dust thresholds (10 mg/m³ inhalable, 3 mg/m³ respirable, ACGIH recommendations for particulates not otherwise classified)
Engineering Controls: Local exhaust ventilation, use fume hood wherever feasible
Personal Protective Equipment: Safety goggles, nitrile gloves, lab coat, dust mask for powder handling

Viscosity: Not applicable
Molecular Weight: 261.7 g/mol
Chemical Stability: Stable under normal handling and storage
Reactivity: Non-reactive under standard laboratory or storage conditions
Possibility of Hazardous Reactions: Contact with strong acids may release citric acid and strontium salts, contact with strong oxidizers could trigger decomposition
Conditions to Avoid: High humidity, temperatures above 200°C, strong acid exposure
Incompatible Materials: Strong acids, strong oxidizing agents
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, strontium oxide may form at high temperatures
Acute Toxicity: Based on similar compounds, very low oral toxicity anticipated, LD50 in rodents estimated above 2000 mg/kg
Skin Corrosion/Irritation: Not classified as corrosive, may cause mild irritation on prolonged contact
Serious Eye Damage/Irritation: Dust may irritate eyes mechanically
Respiratory Sensitization: Dust may irritate nose, throat, and lungs on excessive exposure
Skin Sensitization: No known skin sensitization effects
Mutagenicity: No evidence from available data
Carcinogenicity: Not listed by IARC, NTP, or OSHA as a carcinogen
Reproductive Toxicity: Strontium compounds can interfere with calcium metabolism at very high doses, no effects observed at supplement-level intake
Repeated Dose Toxicity: Long-term studies on strontium citrate are limited, based on analogous compounds, low risk at recommended levels; occupational exposure should avoid chronic inhalation
Ecotoxicity: Strontium ions may accumulate in aquatic organisms, though toxicity to fish and invertebrates is low
Persistence and Degradability: Slowly biodegradable as the citrate structure breaks down in the environment
Bioaccumulative Potential: Strontium can build up in certain organisms, especially under repeated exposure
Mobility in Soil: Moderate to high, depends on soil pH; strontium ions tend to migrate through water-soluble pathways
Aquatic Toxicity: LC50 for aquatic species well above environmental concentrations likely from accidental release
